Do you have a question about the HM31AAE and is the answer not in the manual?
Questions and answers
Power on fridge and freezer not cooling anything at all.
Possible causes of a Hotpoint HM31AAE fridge and freezer not cooling include:
1. The appliance is switched off — ensure the On/Off button is pressed to turn the unit on.
2. The compressor is not running — check if the compressor is operating; if not, there may be an electrical or component issue.
3. The appliance is in defrost cycle — during defrost, the compressor and other loads are disabled, and cooling stops temporarily.
4. A fault or temperature alarm (A1 or A2) — may disable Super Cool/Super Freeze functions and affect cooling.
5. Incorrect temperature settings — ensure the fridge and freezer are not set to high temperatures.
6. Super Cool/Super Freeze functions disabled — these functions assist rapid cooling and may need to be reactivated.
7. Power supply issue — verify the appliance is receiving 240V, 50Hz power.
If none of these resolve the issue, a technical fault may require service.
